Aliases in the EMWAC Internet Mail Services

You can configure IMS to redirect mail using "Aliases".

When IMS processes a message addressed to a local user on the Windows NT system, it checks the recipient's name against an "alias table". If a matching entry is found, the message will be sent instead to the replacement address specified in the table.

Setting up an alias

Select the "Aliases" tab in the EMWAC IMS Control Panel Applet. In the User name: field, type the recipient name you wish to redirect ("foo" for example). In the Map to: field, type the address to which messages should be sent (eg "F.O.O'Riordan@abc.xyz.com") . Then click the Set button.

Now, any messages to foo@thismachine.mycompany.com (assuming your machine is called thismachine.mycompany.com) will be sent on to F.O.O'Riordan@abc.xyz.com.

Note that foo does not need to be a registered user of your machine.

Deleting an alias

Select the alias in the list box and click Delete.

Wildcard aliases

You can specify wildcards in the User name: field. This can be used to redirect mail for all names matching a pattern. For instance, specifying a user name of "T*Y" would match Tony, Tiny, toby, terry, etc. (Note that matching is not case sensitive.)

You can also specify a single wildcard as the first character of the Map to: field. This will be replaced by the actual username when the table entry is used. For instance, if the user name string is "f*" and the corresponding Map to: string is "*-blue@xyz.com", then a message for fargle@thismachine.mycompany.com will be redirected to fargle-blue@xyz.com

This feature can be used to redirect all mail to users at this machine to another machine, by specifying a user name of "*" and a map to address of "*@thatmachine.mycompany.com".

The map table order

The order of entries in the map table is significant. It is processed top-to-bottom, and the first matching entry is used. Thus, specific entries should be positioned near the top of the list, and less specific entries (containing wildcards) towards the end of the list. Use the Up and Down buttons to move entries around.

Import or Export alias entries from or to a text file

You can Import alias entries from a text file. The Import brings up a standard file open dialog.

You can Export alias entries to a text file. The Export brings up a standard file open dialog.

The format for the text file is that each line should contain two fields separated by ":". The first field specifies alias name; and the second field specifies the mapped name. Lines started with a line with "#" are comment.

Here is a sample file:

	# This is a sample file for alias
	Postmaster: administrator
	alias1: user1
